Unable to refund a keystone passive with nothing allocated in radius

I am playing Oracle with the Entwined Realities passive.

I socketed a Controlled Metamorphosis Diamond with a medium-small radius into a jewel socket. I then allocated a point into Zealot's Oath.

I allocated a point into Desensitisation and then refunded the passive. I can no longer refund the Zealot's Oath keystone. Nothing in the medium radius of Zealot's Oath is allocated.

Same bug here - different keystone but same symptoms. Entwined Realities, nothing allocated in the radius, can't refund the keystone :(

Hi, One of my friends just ran into this issue on his oracle, specifically with scarred faith, it turns out the oracle ascendancy seems to disconnect some passives from the tree, even if they should be connected if they were not an oracle.

Try refunding every non-attribute passive in the radius of the keystone you're having the problem with.
